Title: Method and device for controlling speed of induction motor without sensor
Inventor: IWAMI TAKAHIRO
IPC: H02P23/07
Filed: 1994-03-23
Abstract: PURPOSE:To provide a method and device for controlling speed of induction motor without sensor by which the speed of an induction motor can be accurately estimated even at a transition time. CONSTITUTION:At the transition time of the speed change of an induction motor the calculated actual value phi2(n-1) of the secondary magnetic flux vector of the induction motor is found from data obtained in the last sampling period (n-2) even when the actual angular velocity of the motor becomes different from an estimated angular velocity LAMBDAomegam(n-1) and a secondary magnetic flux vector LAMBDAphi2(n) calculated based on the estimated angular velocity LAMBDAomegam(n-1)) becomes largely different from the actual secondary magnetic flux vector. Then the estimated velocity is corrected in the direction in which the phase difference DELTAPSIbetween both actual secondary magnetic flux vector phi2(n-1) and calculated secondary magnetic flux vector LAMBDAphi2(n-1) decreases by comparing both vectors with each other.

When the test communication is the test communication from the master processor 11, the call control processing unit 12 requests an output of reply communication A1 to the execution control section 7. When the test of all processing units is finished in this way, the master processor 11 compares the signal processing unit registered in a prescribed area of the common memory device 5 with all the signal processing units, detects a signal processing unit not registered to apply fault processing and clears the display of test execution state.
